[PATCH v2 0/2] Add memcg accounting to Arm KVM

[Jia He]

Inspired by what had been done by X86 kvm and kvm common codes, it would
be better to make arm64 kvm consistent with them.

The memory allocations of VM scope should be charged into VM process.
Hence change the allocation flag from GFP_KERNEL to GFP_KERNEL_ACCOUNT.

There remain some GFP_KERNEL unchanged since they are global allocations,
instead of VM scope.

Changes:
v2: address a few comments from Marc Zyngier, including redundant
    GFP_KERNEL, incorrect memcg accounting and variable type   
v1: https://lkml.org/lkml/2021/9/2/649
